STORAGE BATTE RY.V

SPECIFICATION forming part of Letters Patent N0. 765,082, dated July 12,1904.

Application filed August 9, 1902.

To 'I1/ZZ wit/)m t may concern- Bc it known that I, IsIDoR KITSE u, a citizen of the United States, residing at Philadelphia, in thel county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Storage Batteries, of which the following isa specification.

This invention relates to improvements in electrical accumulators, or, as more commonly known, storage batteries.

' In that class ot batteries wherein the electrodes are formedof lead plates to which is applied a suitable' coating of active material,

usually oxid of lead, it is a well-.known fact that the exposed surfaces of the lead become in time unduly brittle and warped, and, moreover, it is also a well-known. fact vthat batteries of the class referred to are extremely cumbersomeand heavy andV that their capacity is comparatively small in proportionto their great weight. i

It is therefore the object fof the present invention to provide a storage battery the construction of which is such as to eftec'tually overcome the objectionable features above noted and one which is of large capacity, but at thesame time much lighter in proportion toits capacity than the batteries now generally in use. l i y With these general objects in View and others which will appear as the nature of the improvements is better understood the invention consists,l substantially, in thenovel construction, combination, and arrangementof parts as will be hereinafter fully described',

illustrated in the accompanying drawings, and

pointed out in the appended claims.

In the drawings, Figure l is a vertical transverse sectional View of .a battery conthe battery removed from the containing-jar,`

the side cover and the 'active material being removed. Fig. 3 is a sectional perspective L View of the frame of the battery. Fig. 4 is the usual containing-jar.

tive view thereof. specti've view of the frameof the form shown .in Figs. 5 and 6, and Fig.' 8isjatop plan view of such form. Referring to the drawings, the numeral l designates tlie usual containing jar or vessel ot' a storage battery; but as this does not enter into'the present invention it is suiiicient to state that the same may be of any desired construction and form.

Arranged within the containing jar or vessel 1 is a cell 2, and said cell comprises a frame 3, which is substantially rectangular in form. The frame 3 is preferably formed of hardrubber or other material which will not be attacked by the electrolyte within the containing jar or vessel, and said frame is.

provided at each of its edges and xextending entirely around the same with a rabbeted portion 4, through the medium of' which a shoulder 5 is formed at such edges. is also providedl at its central portion and ex- The frame-3y The slots 7 reg-- Fig. 7 isa sectional pertending entirely around the saine with an in-r terior thereof, as will appear more,- fully here` inafter. .l

Arranged within the'frame 3 at the sides of the iange' or bead 6 and itting snugly there againstis a pair of suppbrting-plates 8, and

said plates are formed of porous .material in' -order that the electrolyte conlined within the area `between said plates when the cell is placed within the containing jar or vessel 1 may be absorbed by said plates and passed therethrough. The plates 8 are also lproviole'i'4 at their outer faceswith of outWtIdly- .projecting 'pins 9, 'said pins being-:arranged preferably in staggered relation inf' order to provide supports for a conductorj l0. The

conductor 10 is-infthe form of a thin strip,

preferably of lead, and s aid conductor is wound about the pins 9 in. a eircuitous manner, as

clearly shown in Fig. 2, and arranged on said Fig. G'isaperspecpins in suchfmanner that the outer edges' of IOO ' said pins and strip in such manner as to 'completely'envel'op the same, and in order that the active material may be held vwithin the frame 3 andupon the plates 8 said frame is provided with removable covering-plates 13.

The latter, as is the lcase with the plates 8, are

, formed of a porous material through which the electrolyte may readily pass in order to reach the active material; but it will be observed thatthe length .of the pins 9 and the. width of the strips 10 are no t sufcient to contact with the inner sides of thel plates 12.

:Hence'a space remains between said plates ycontaining jar lor vessel 1.

Aand the extremities of the pins 9, which spaces are lfilled with'the activelmaterial 12, as is clearly seen Vin Fig. 1. 1

In Figs. 5 to 8, inclusive, is shown another form of' the battery, and this form is designed for use without the employment of the usual The form shown in the figures referred to is precisely the same in all respects to the form shown in Figs. 1 to L1, inclusive, with the exception that in lieu of providingr the bottom of the containing-frame 3 with a slot, as is the casein the form shown in Figs. 1 to 4, such 'slot is entirely omitted, so that the lower end of the frame remains closed. In this ferm the electrolyte is placed within the cell through the slot7 at the upper end thereof and occupies the space between .the supporting-plates 8, and it wcill also be observed that in lieu of forming the-coveringplates 13 of porous material such plates are formed of a non-porous material. Consequently the electrolyte is precluded passing through -the covering-plates, and hence lealiage of the cell is entirely prevented.

It is obvious that in each of' the forms of. the invention shown one of the supportingplates 8 and its pins 9 and conducting-strip 10 will form the 4positive electrode, while the other` supporting-plate and its pins and conducting-strip will form the negative electrode,

and by reason of the construction shown and described it is also obvious that a battery is provided which is comparatively light, but of great capacity, and one in which there are no exposed surfaces of lead to become in time unduly brittle and warped.

While the forms o-f the invention herein shown and described are what are believed to be preferable embodiments thereof', it will of course be understood that the same are sus-` ceptible of various changes in the form, proand the right' is therefore reserved to modify or vary the invention as falls within the spirit and scope thereof.

Having thus described my invention, what is claimed as new, and desired to be secured by Letters Patent, is

7 1. A storage battery, comprising a containing-.frame provided with an inlet for the electrolyte, a support arranged therein, a conductor carried by said support, and a body of active material confined within said frame and enveloping said conductor.

2. A storage battery, comprising a contain- 'ing-frame, a support arrangedltherein, a series of pins carried by saidsupport, a conductor carried by said pins, and a body of active material arranged within said frame and enveloping said conductor and pins. l

3. A storage battery, comprising a containing-frame, said frame being provided lwith an internal iiange or bead, supports arranged within said frame and fitting upon said fiange4 or bead, conductors carried by said supports, and abody of' active material confined within said frame and enveloping said conductors. 4. A storage battery,l comprising'a containing-frame, .said frame beingprovidedwith an internal Harige or bead having an inlet for the admission of' the electrolyte, supports fitted upon said flange or bead and spaced from each other to provide a confined area for the elec'- trolyte, -conductors carried byl said supports, and a body of active material confined Within said frame and enveloping said conductors.

5. A storage battery, comprising a containing-frame, said frame being provided with an internal flange or bead and having an inlet for the-admission of the electrolyte, supports {itted upon said iiange or bead and spaced from each other to provide a confined areal for the electrolyte, pins carried by said supports, conductors carried by said pins, and avbody'of active material confined within said frame and enveloping said pins and said conductors.

6. Astor-age battery, comprising a positive and negative electrode, both electrodes contained in one containing-frame provided with an inlet for the electrolyte, and 'a porous support for the conducting and active material lfor each of said electrodes.
